PALLET CONTAINER Filed June 5, 1965 2 Sheets-Sheet 2 FIG. 6

United States Patent 3,281,049 PALLET CONTAINER Gerald G. Avitable, Northford, Conn., and William T.

Dailey, Manhasset, N.Y., assignors to Interstate Container Corporation, New York, N.Y., a corporation of New York Filed June 3, 1965, Ser. No. 460,912 12 Claims. (Cl. 229-23) This invention relates to containers, and more particularly to a pallet container for unit loading.

Unit loading, or the shipment of smaller parcels and cartons in a large container, has proved convenient and economical. In fact R.E.A. Express, (formerly The Railway Express Agency) offers a substantially lower rate for such shipments, because the large unit goes to a single consignee, with greatly reduced paper work for all concerned. Moreover, the large container for unit loading is palleted or designed for mechanized handling by means of a fork lift truck. R.E.A. Express supplies the large containers to shippers free of cost, in order to encourage such unit loading.

Sometimes collapsible metal cages are used, but these are costly and must be returned. It has also been suggested to use expendable containers made of corrugated paper board, wit-h skids at the bottom. The primary object of the present invention is to generally improve such containers.

More specific objects are to provide a container which is easy to manufacture, there being no complicated shapes to make, and which is economical in the use of material, it consisting of two simple rectangular sheets.

In accordance with a further feature and object the containers are supplied to the shipper in knocked-down form, and with the sheets flat and therefore easily and compactly shipped and stored. No factory closure or assembly of parts is required, the entire assembly operation being readily performed by the shipper at the loading point.

Another object is to facilitate loading the container with the smaller cartons, which in some cases, for example cartons of liquor, may be quite heavy, and to this end the present container is so designed that it may be side loaded as well as top loaded.

The container comprises two sheets of corrugated paper board disposed in crossed relation at the bottom, thus providing a bottom of double strength. In accordance with still further features and objects of the invention, individual pallet feet are employed thus affording fourway entrance by the fork of a fork lift truck; the pallet feet are so designed that they help lock the two sheets in registry at the bottom of the container; and conversely, the double thickness bottom helps provide a desired sturdy mounting of the pallet feet on the container.

To accomplish the foregoing general objects and other more specific objects which will hereinafter appear, our invention resides in the shipping container elements and their relation one to another, as are hereinafter more particularly described in the following specification. The specification is accompanied by a drawing in which:

FIG. 1 is a perspective view showing a closed shipping container embodying features of the invention;

FIG. 2 is a perspective view showing the container partially assembled and open for top loading;

FIG. 3 is a perspective view showing the container left open at the side and top for easier loading;

3,281,049 Patented Oct. 25, 1966 FIG. 4 is a plan view of one of two sheets making up the container;

FIG. 5 is a plan view of the other sheet;

FIG. 6 is a section drawn to larger scale through a pallet foot forming a part of the container;

FIG. 7 is a fragmentary vertical section taken approximately in the plane of the line 7-7 of FIG. 1 but drawn to larger scale;

FIG. 8 is a plan View showing two sheets in crossed relation, for assembly into a container having a length, width and height which differ from one another; and

FIG. 9 is a fragmentary section showing a different form of pallet foot which may be used as a part of the container.

Referring to the drawing, and more particularly to FIG. 1, the container 12 is assumed for simplicity to be equal in length, width and height. As is customary in this work it is completed by tapes or bands 14, 16 and 18 secured tightly therearound. It will be understood that a greater number-of tapes may be employed if desired, depending largely on the size of the container, and on the weight of the goods being shipped. Any of the known or standard methods of taping may be employed, using tapes made of metal, fiber or plastic, and secured at their ends in any known fashion, as by means of metal clamps or clips, applied by any of the usual tensioning devices.

The tapes are readily passed beneath the bottom of the container because of the pallet feet 20. These are preferably round or cup-like in order to facilitate four way entry by the fork of a fork lift truck. For smaller containers four pallet feet are adequate, these being located near the corners. For larger containers a fifth foot is added, this being located at the center of the bottom of the container.

Refenring now to FIG. 2, the carton 12 is shown preliminarily assembled, with the top open for loading. This is prior to the addition of the tapes or bands shown in FIG. 1. However, it would be possible if desired, to apply one or more horizontal tapes around the body of the container before loading. FIG. 2 also shows how the top is made up of two pairs of half panels, the half panels of each pair resting edge to edge when closed.

One advantage of the present container is the ease of loading the same, even with heavy cartons. This is so because the container may be side loaded as shown in FIG. 3, in which the partially assembled container is shown open at both the side and top, so that the smaller cartons (not shown) being loaded into the large container do not have to be lifted over the top of the container.

The container is made up of two simple fiat rectangular sheets which are disposed in crossed relation during assembly. These initially flat rectangular sheets are illustrated in FIGS. 4 and 5, and for simplicity of description the container is first assumed to be a cube, that is the length, width and height are all equal. In passing, it may be mentioned that in the present description, and even when these dimensions differ from one another, the terms length and width mean merely that the dimensions are transverse to one another, rather than that one is longer than the other.

Referring to FIG. 5, there is a first flat rectangular sheet 22 of corrugated paper board having a width equal to the length of the container, and a length equal to twice the width and height of the container. This sheet is scored transversely as indicated by the broken lines 23, to define a bottom 24, two side panels 26, and two half panels 28 for the top. The side panels 26 have edge located half waybetween the top and bottom of the container. The term score here means an indentation for folding, rather than a out. In preferred form, the bottom 24 has holes 32 punched therethrough for pallet feet.

The second fiat rectangular sheet 34 is shown in FIG.

I 4, and it has a width equal to the width of the container plus the width of two corner flaps 36, and it has a length equal to twice the height and length of the container. This second sheet is scored by means of transverse score lines 38 to define a bottom 40, and by score lines 42 to define two side panels 44, and also two half panels 46 for the top. Additional score lines 48 parallel to the long edges of the sheet define the corner flaps 36 at the edges of the side panels 44, and edge flaps 50 at the edges of the bottom 40, and additional edge flaps 52 at the edges of the half panels 46. The bottom 40 has holes 54 which are so located as to register with the holes 32 of the first sheet 22 when the sheets are disposed in crossed relation. When the bottom is square, as in this special case, the holes might register in either orientation, but the intended registration is with the sheets in crossed relation.

The second sheet 34 is notched at 56 to separate the edge flaps 50 and the corner flaps 36. It is also notched at 58 between the corner flaps 36 and the edge flaps 52. These notches are of full depth, that is, they are as deep as the flaps are wide. The corner flaps 36 are notched at 60 in proper location to interlock with the aforesaid notches 30 of the first sheet 22 when the sheets are assembled. Usually and in this case they are located half way between the top and bottom of the container. It should be noted that the notches 30 and 60 are of half depth, that is their length is only half the width of the corner flaps 36.

The knocked-down container kit preferably includes pallet feet, and one of these is shown in FIG. 6. It comprises an inverted, generally cylindrical cup 62 designed to be disposed beneath the double bottom 40, 24 of the container, and it further comprises a fastener 64 designed to pass through the aforesaid holes 54, 32 and to be received in the cup 62 with a snap fit. More specifically, the fastener 64 comprises a flat circular head 66 of large area, and a tubular shank 68 the lower end of which is enlarged at 70, and longitudinally slit at 72 to make the same resiliently compressible. In the present case there are four such slits in quadrature. The cup 62 and fastener 64 may be made of any suitable material, and in the illustrated case they are molded out of a moldable plastics material, specifically a cellulose acetate plastic commercially known as Tenite. It is designed to support 2,000 pounds.

The cup 62 is molded integrally with a socket portion 65, and with radially disposed reinforced webs 67. It will be understood that the resilient shank 68 is received in the main body with a snap fit, thus anchoring the parts 62 and 64 together and to the bottom 40, 24. This foot has the advantage of locking the bottom panels 24 and 40 together, and at the same time the double thickness bottom helps insure sturdy mounting of the foot on .the container.

The method of assembly will beevident from the foregoing description, the first strip 24 preferably being' disposed transversely over the second strip 34, with the bottom panels and the holes in registration, whereuponthe pallet feet are applied by passing the'fasteners through the holes and into the feet. The side panels 26 of the upper sheet are turned upward on score lines 23; the corner flaps 36 are folded on score lines 48; the side panels 44 are turned upward onscore lines 38; and the notches 30 and 60 are interengaged so that the lower half of each flap 3 6 is on one side of panel 26, while the upper half is on the other side. As shown in FIG. 2 the lower half of the flap 36 is on the outside of panel 26, and the upper half is on the inside. This will also be clear from inspection of FIG. 7, showing the upper part of flap 36 4 inside panel 26, and the lower part of flap 36 outside panel 26.

When the carton has been filled the half panels 28 are turned inward, and then the half panels 46 are turned inward over the half panels 28. At this time the edge flaps 50 and 52 may tend to expand outward somewhat, but later are held in desired folded position by the tapes or bands as shown in FIG. 1. The flaps 50 and 52 are not as important as the flaps 36, and are not wholly essential to assembly and use of the container, but they are desirable because they help stiffen and strengthen the container, and are anyway formed out of what would otherwise be scrap board which would have to be cut away from the rectangle shown in FIG. 4.

For side loading as illustrated in FIG. 3 it is merely necessary to delay turning up one of the two side panels 44.

As so far described the container is assumed to be a cube, but there is no need for this, and in most cases the length, width and height would differ from one another. FIG. 8 shows two crossed rectangular sheets proportioned to produce a container having a width of four feet, a length of five feet and a height of three feet. In such case the first or upper sheet has a width of five feet, and a length of 14 feet. Assuming the edge flaps of the lower sheet 82 have a width of four inches, the lower sheet would have a width of four feet eight inches, and a length of 16 feet.

As before, the first sheet 80 is scored to define a bottom 84, two side panels 86 and two half panels 88. The side panels 86 have edge notches 'with a depth of two inches. The bottom panel 84 has holes for the fasteners of the pallet feet, and in the present case there are five holes 92, four in the corners as before, and the fifth at the center of the bottom. The bottom panel 84 is four feet by five feet; the side panels 86 are five feet by three feet, and the half panels 88 are five feet by two feet.

In this connection it will be understood that the term half need not be taken literally, and is intended more broadly to mean that the panels 88 are partial panels which fold in edge to edge relation to cover the top of the container. Thus in the present case one panel 88 might be three feet wide and the other one foot wide, adding to the desired four feet, instead of being two feet each. However, the symmetrical arrangement shown is usual and preferred. 7

The lower sheet 82 is scored transversely to define a bottom which is directly beneath the bottom 84, and to define side panels 94 which are four feet by three feet, and half panels 96 which are four feet by two and onehalf feet. Here again the half panels need not be equal in width but their summed widths preferably equals five feet.

There are also longitudinal score lines which define corner flaps 98 having a width in this case of four inches, and having edge notches 100 with a depth of two inches, and appropriately located to mate and interlock with the aforesaid notches 90 of the first sheet. The longitudinal score lines also' define edge flaps 102 for the bottom, and edge flaps 104 for the top. The corner flaps and the edge flaps are separated by notches 106 which have the full depth of four inches.

The bottom panel of the second sheet 82 has five holes which register with the five holes 92 of the first sheet,

and pallet feet like that illustrated in FIG. 6 are applied to the crossed sheets when assembling the container.

'It is not essential that the pallet feet be two-part feet which fasten through holes, and in FIG. 9 we show another type of pallet foot which we have used on the present container. In this case the foot is a somewhat tapered cup 110 having a closed bottom 112 and a flat peripheral flange 114. It may be molded out of a suitable plastics material. It is secured to'the bottom 116 of the container by means of a fabric attaching ring 118 the upper face of which is coated with a self-sealing or pressure sensitive adhesive, and which fits around the foot and may be pressed against the flange 114 and the bottom 116, and partly around the side panel 120 as shown in 122. Pallet feet of this type are commercially available, the adhesive disk 118 being initially protected by a suitable release disk which is peeled off the adhesive surface before applying it to the bottom of the container.

The dimensions given above must be considered to be approximate rather than exact because in practice the dimensions may be and preferably are modified slightly to allow for the thicknesses of the corrugated paper board. The interlocking notches 90 and 100 in FIG. 8 may have a depth slightly greater than two inches, when the corner flaps have a width of four inches, in order to facilitate easy assembly. The flaps of these containers may have a width of from say four to six inches, depending on the size of the container. The corner flaps may have more than one notch each, particularly when the container is very high. With two notches as in FIG. 8 there would be three sections of corner flaps, two of which could be outside and the middle one inside, or vice versa. We recommend notches at intervals of about one foot. A

carton four feet high then would have three notches in each corner flap.

It is believed that the construction and method of assembly and use of our improved shipping container, as well as the advantages thereof, will be apparent from the foregoing detailed description. The new container is easy to manufacture and involves no complicated shapes. The two sheets of corrugated board are essentially rectangular, and are therefore economical in the use of the material, as well as simple to manufacture. We estimate a saving of one-third in the amount of board needed. No assembly or closure of parts is required to be done by the container manufacturer. The sheets are stacked and shipped in flat condition, with minimum shipping cost and space requirement. In use the sheets are locked together by their crossed relation, and by the interlocking corner flaps, and when two-part pallet feet are used the sheets are additionally secured together by the pallet feet.

The construction of the container is such that it may be made in any desired dimension, including the standardized dimensions recommended by R.E.A. Express. The container has the advantage, particularly when it is substantial in height, of affording side as well as top loading. The pallet feet permit four way entry by the fork of a fork lift truck. The container is completed by tapes or bands which may be any of the knowntapes, applied by any of the known tightening and fastening devices. The container is inexpensive and therefore expendable after being unloaded. Unloading is convenient and fast because one or more or all of the side panels may be dropped.

It will be understood that while we have shown and described our invention in several preferred forms, changes may be made without departing from the scope of the invention, as sought to be defined in the following claims. In the claims the terms length and width are used in a relative sense, and refer to two relatively transverse dimensions, but the width could be greater than the length. The reference to half panels for the top is not intended to require that they be truly half or equal. The dimensions given in the claims are to be considered approximate rather than exact, as previously explained.
